目的 :观察应用NIR冠状动脉支架治疗血管分叉处病变的临床及冠状动脉造影的结果。方法 :将36例冠状动脉分叉处病变的患者均置入NIR支架 ,并观察患者发生临床事件及6个月后的冠状动脉造影结果。结果 :6个月后完成临床及冠状动脉造影随访的患者32例 ,无1例发生急性冠状动脉闭塞、急性心肌梗死 ,3例发生了内支架再狭窄 (9 38 % ,直径>50 % ) ,仅有1例发生再狭窄后出现心绞痛 (33 3% ) ,3例分叉处血管发生再狭窄 (9 38 % ,其狭窄程度>60% ) ,有1例于术后第10天出现急性肺栓塞死亡。结论 :冠状动脉血管分叉处病变的患者经皮冠状动脉腔内成形术 (PTCA)成功后置入NIR支架 ,其发生临床事件及再狭窄率低 ,近、远期临床疗效及预后好
Objective: To observe the results of clinical and coronary angiography in the treatment of vascular bifurcation lesions with NIR coronary stent. Methods: Thirty-six patients with lesions at the bifurcation of coronary artery were placed in NIR scaffolds. The clinical events and 6-month coronary angiography were observed. RESULTS: Thirty-two patients were followed up for clinical and coronary angiography 6 months later. None of them had acute coronary occlusion or acute myocardial infarction. Stent restenosis (9 38%, diameter> 50%) occurred in 3 patients. Only 1 patient developed angina (33 3%) after restenosis, 3 patients had bifurcation restenosis (9 38%, stenosis> 60%), and 1 patient developed acute lung injury on the 10th day after operation Embolic death. CONCLUSIONS: Percutaneous transluminal coronary angioplasty (PTCA) in patients with lesions at the bifurcation of the coronary arteries has been introduced into the NIR scaffold. The incidence of clinical events and restenosis is low, and the clinical outcome and prognosis are good in the short and long term
